While testing on my local environment I use a CORS plugin to be able to do this kind of request .However when deployed im getting the CORS error. How can I bypass this limitation so that newsletter works on my live site. The error im getting is the following.

@luisfoundation our APIs don't support CORS requests, so if you're using JavaScript for this, you'd need to send the data from the page to your server, and then have your server make the request to HubSpot.

Is this on your roadmap to add? Would be very convenient as we're using a static site builder so have no backend to submit to. Currently our forms submit to FormBucket but would like to submit these directly to HubSpot.

@ozzyonfire Could you host your own server to proxy the data through to HubSpot? You could make an AJAX request to your own server and then make the proper server-side request to HubSpot to submit the form data.
